地质钻探之绳索取芯

Rope for core in geological drilling

绳索取芯钻探是一种不提钻而由钻杆内捞取岩心的先进钻进方法,它的结构简单,施工效率高,操作难度也不算大,是一种有效提高钻探效率的新技术,然而作为新技术,自然也有其优劣之处,在钻探过程中,也容易产生一些新的问题,那么我们该如何去应对以及提高绳索取芯的工作质量就成了当代钻探人员的首要研究任务之一。只有认真的研究钻探方案,因地制宜的做好钻探工作,才能提高绳索取芯的效率,降低成功,提高工作质量。

Wireline coring drilling is an advanced drilling method that takes cores from the drill pipe without lifting the drill.Its structure is simple,its construction efficiency is high,and its operation is not difficult.It is a new technology that can effectively improve the drilling efficiency.However,as a new technology,it naturally has its advantages and disadvantages,and it is easy to produce some new problems in the drilling process,So how to deal with and improve the quality of wireline coring has become one of the most important research tasks of contemporary drillers.Only by carefully studying the drilling plan and doing well the drilling work according to local conditions,can we improve the efficiency of wireline coring,reduce the success and improve the work quality.
